Electronic Stability Program (ESP) is a patent of Bosch Company.
ESP system is actually a traction control system. Compared with other traction control systems, ESP can control not only the driving wheel but also the driven wheel. For example, rear-wheel drive cars often turn too much. At this time, the rear wheel is out of control and the ESP will slow down the outer front wheel to stabilize the car. When the steering is too little, ESP will slow down the inner rear wheel to correct the tracking direction, thus correcting the driving direction. ESP system is an important system in automobile, which usually supports ABS and ASR. It helps the vehicle to maintain dynamic balance by analyzing the information of vehicle running state from various sensors and then sending rectification instructions to ABS and ASR. ESP can keep the vehicle in the best stability in all situations, especially in the case of oversteer or understeer. ESP generally needs to install steering sensor, wheel sensor, sideslip sensor, lateral acceleration sensor, etc. These sensors well support the operation of the ESP system. ESP system is only used in some high-end cars, but not in some scooters. This is mainly because the price of ESP system is still relatively expensive. Therefore, as a sensor manufacturer, we should actively develop sensors on it, and strive to reduce the price of sensors and apply ESP system to every car to ensure driving safety.
